PORTABLE STOVE.

SEECIIEIGATION forming part of Letters Patent No. 716,501, dated December 23, 1902- Application filed May 14, 1902. Serial No. 107,340. (No model.)

To all whom. t 71u14/ concern,.-

Be it known that I, JAMES WATSON, a citizen of the United States, residing at Marinette, in the county of Marinette and State of Visconsin, have invented a new and useful Portable Stove, of which the following is a specication.

My invention is an improved portable stove adapted for use in baking bread, roasting meats, and general cooking purposes in lumbering and other camps; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

The object of my invention is to provide an improved stove of this class which is eX- ceedingly light and portable, which is adapted to be disassembled, so that the parts thereof may be carried separately, which is practically air-tight when set up, and which is adapted to be used in connection with either one or two baking or roasting ovens, as may be desired.

In the accompanying drawings, Figure 1 is a perspective view of a portable camp-stove embodying my improvements, showing the same provided with two ovens. Fig. 2 is a similar view showing the stove provided with one oven. Fig. 3 is a detail perspective view showing the detachable side member of the stove. Fig. 4 is a similar View showing the bucket or tank for heating water. Fig. 5 is a vertical transverse sectional view of my improved portable stove. Fig. 6 is a horizontal sectional view of the same.

The top member 1 of the stove is preferably made of sheet metal and is formed with downturned ilanges 2 3, respectively, at its sides and ends. The rear side member 4 of the tire-box of the stove is formed, preferably, of a sheet of metal. The upper end thereof is connected to the under side of the top 1 at the rear end thereof by a hinge 5, which enables the rear member 4 to be folded under the top. The rear member4 has its sides provided with inturned flanges V6, which are on the inner face thereof and at a slight distance therefrom, grooves 7 being thus formed between the said inturned flanges 6 and the inner side of the said rear member 4. On the inner side of the latter at the upper end thereof are upwardly diverging inclined guide-flanges S, which in practice are struck up from a piece of iron 9 of appropriate size and shape, the same being secured to the inner side of the rear member or Wall of the fire-box by rivets or otherwise, as may be preferred.

At the front end of the top 1 and depending therefrom for a slight distance is a front section 10, which in practice is preferably formed integrally with the top 1, and to which is connected the upper end of the fire-door 11 by a hinge 12, as here shown, ora plurality of suitable hinges. The front end section 10 is formed at its vertical sides with inturned flanges 13, which are similar to the ianges 6, hereinbefore described. The top 1 is provided at its rear end with a smoke-escape opening and a collar 14 around the same adapted to iit the lower end of a suitable stovepipe, so that an efficient draft may be secured.

The side members of the stove may be ovens, or an oven maybe used for one side member of the stove and a metal sheet 14 may be used for the other side member thereof. In Fig. 2 of the drawings I show the said metal-sheet side member 14 in connection with an oven 15, which forms the other side member, and in Figs. 1, 5, and 6 of the drawings I show a pair of such ovens 15, which form the side members of the stove and are detachably connected to the top and the rear member 4. The ovens are alike in construction, and I will describe one of them. The oven comprises an inner lining 16, which in practice is preferably made of sheet-tin, and an outer casing 17, which in practice is preferably made of sheet-iron. The lining is fitted closely in the casing of the oven and corresponds therewith in shape. The outer side of the oven is vertical, as at 18, and the upper portion thereof is inclined upwardly and inwardly, as at 19, and formed with an upstanding iiange 20, which is adapted to engage the inner side of one of the side iianges 2 of the top. The outer side and end walls of the oven extend below the bottom 2l of the oven to form a chamber 22, the inner side 23 of which is open and communicates directly with the fire-box when the stove is set up. The inner Wall 24 of the oven is vertical and the bottom 2l thereof is preferably horizontal. Those portions of the inner side wall IOO and bottom-of the oven which are nearest the fire and exposed to the greatest heat are preferably reinforced vby a casting 25, which comprises a vertical Web or flange 26 and a horizontal web or flange 27, joined at the angle formed thereby. The said reinforcing-piece may be riveted or otherwise suitably secured to the lower inner corner of the oven. A vertically-disposed protecting-plate 28 extends longitudinally in the oven near the inner wall thereof and is here shown as formed at its ends with flanges 29, which bear against and are riveted to the end wallsof the oven. This protecting-plate prevents the baking or roasting pan from getting too close to the inner side of the oven, where it is heated to a high degree, and prevents the bread or meat which is being baked or roasted from being burnedv on the side nearest the inner side of the oven. This device also forms a brace whereby the front and rear ends of the oven are connected and which serves to a considerable extent to insure stiffness and rigidity of the device, which, being mainly constructed of sheet metal, has need of being thus reinforced. The points at which the front ends of these bracing devices are attached are adjacent to these sides of the door-openings, which are practically the most exposed parts of the oven and most in need of reinforcement. A reflectingplate 29' is disposed in the chamber 22 under the bottom of the oven, is laterally inclined upwardly and outwardly, as shown in Fig. 5, and is formed at its outer side with a flange 30, which is riveted or otherwise suitably secured to the outer wall of the oven directly below the bottom thereof. The door 31 of the oven may be either at the end thereof, as here shown, or at the outer side thereof. The door is preferably hinged at its lower side, as at 32, and is provided with a suitable device 33 for securing it in a closed position. At the inner corners of the oven, at the front and rear ends thereof, are outwardly-extending flanges 34, which are adapted to engage the flanges 6 13 at the front and rear ends of the fire-box of the stove and to form interlocked connections between the same and the oven. When assembling the parts of the stove, guide-flanges S engage the inner sides of the ovens and force their flanges 34 into the grooves 7 in the rear and front end plates or sheets of the fire-box and effect closely-fitting joints between the flanges 2 of the top and the flanges 2O on the upper sides of the ovens. The angle of the inclined upper portions 19 of the ovens is such as to cause heat to be deflected downwardly and inwardly in the ovens, and the reflecting-plates 29 serve to reflect heat from the fire-box upwardly and extend the same outwardly under the bottoms of the ovens, so that the ovens are uniformly heated throughout their entire extent and the contents thereof are enabled to be perfectly baked or roasted therein without the necessity of turning the pans in the ovens during the baking or roasting process. The

ovens are practically. air-tight, so that the same retain the moisture arising from the articles which are baked or roasted therein,with the result that the 'same are perfectly baked or roasted without the formation of a hard crust thereon.

When only one oven isin use, the opposite side of the fire-box or combustion-'chamber in which the wood is burned is formed by the plate or sheet 14, the upper side of which bears under the top 1 and against one of its side flanges 2, and the said plate or sheet is formed at its ends with outturned flanges 14a,

which are similar to the flanges 34, with which the ovens are provided, and are adapted to engage the grooves 7 and 13 of the front and rear walls or ends of the fire-box. At the lower rear corner of the sheet or plate 14 is a plate 35, which is here shown as riveted to its outer side and formed with a flange 36, which engages the outer edge of the rear wall or member 4 and prevents inward lateral displacement of the said side sheet, plate, or member 14. The door 11 is provided with side flanges 11a, which overlap the flanges at the front ends of the ovens or side members. The flanges 34 at the front and rear ends of the ovens are bent outwardly from sheets or plates 37, which are riveted or otherwise secured to the inner sides or walls of the oven, and the lower ends of which are turned outwardly and disposed horizontally, as at 38, to form supporting-feet under the inner corners of the ovens. v The ovens are formed or provided on their rear ends near theirinner corners with sheets or plates 39,which have guide and securing flanges 40, that are adapted to engage and overlap the sides of the rear sheet or member 4 of the re-box of the stove.

rThe door 11 is shown as provided with a rod or wire 41, pivotally connected to the lower side thereof and having its outer end downturned, as at 42, and adapted to be stuck in the ground to hold the door either partly open to any desired extent or to fasten the door in a closed position. Hence the draft may be readily regulated.

In Fig. 4 of the drawings I show a vessel 43 for heating water, which vessel is preferably of semicylindrical form, or approximately so, to provide a flat side adapted to be placed against the rear end of the fire-box of the stove, the said vessel being adapted to stand on the ground in rear of the stove, so that water in said vessel will be heated. The said vessel is also preferably provided with a bail 44, whereby it may be readily carried, and with a removable lid 45. It will be understood that the top of the stove may be utilized for frying, boiling, or other cooking purposes.

Having thus described my invention, I claim- 1. A stove having a fire-box provided with a direct smoke-exit, an oven forming one side of the fire-box and a shield within said oven forming a brace spaced from the inner side IOO IIO

IZO

thereof, and connected with the front and rear ends and With the bottom of the oven, substantially as set forth.

2. A portable stove of the class described comprising side members having flanges on their upper sides, one of said side members being an oven, and said side members having ontturned flanges at their ends, end members having inturned flanges at their sides to engage the flrst-mentioned flanges and thereby form interlocked connections between said side and end members, and a top having downturned flanges to engage the outer sides of the top flanges of the side members and also engage and overlap the upper ends of the end members, substantially as described.

3. In a stove of the class described, a top having ends connected at their upper sides thereto, and having inturned flanges at their vertical sides one of the ends having a door portion, in combination with side members having outturncd flanges at their ends to form (D KDD detachable interlocking connections with the irst-mentioned flanges, substantially as de scribed.

4. In a stove of the class described, a top having depending side flanges, in combination With end members connected at their upper ends to the ends of the top and having inturned flanges at their sides one of the ends having a door portion, and side members having outturned fianges at their ends to form detachable interlocking connections with the anges of the end members and having up- Wardly-extending anges at their upper sides to engage the depending anges of the top, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

JAMES WATSON.
